Engines and related Systems
The engines of the rotorcraft are controlled by FACEC (Full Authority Digital Engine Control). This computer controls rotor RPM as function of density altitude as shown in the following figure. Tumbler on Engine Control Panel provide access to FACECs (2) and Engines (1). Refer to the checklist for further informations.
To improve performance in CAT-A situations or with a gross mass above 2825 kg, the rotorcraft is equipped with a system that automatically increases rotor RPM by up to 3 %. The system is armed by pressing HI-NR Mode button. When armed, HI-NR Mode will be activated while speed is less then 55 KIAS. A green caution light above the Master Caution Light indicates this.
Information will be coming soon...
